工作中 cmakelist 的积累

Demo 记录

• main.cpp

  #include <stdio.h>
  #include
  include "baz.h"
  using namespace std;

  int main()
  {
  DataBuffer db(10);
  cout << " The value of db is " << db.data<< endl;
  }

• baz.h

  class DataBuffer
  {
  public.
  DataBuffer(int data);

  public:
  int data;
  };

• baz.cpp

  #include <stdio.h>
  #include
  include "baz.h"
  using namespace std;

  DataBuffer::DataBuffer(int data) : data(data)
  {
  }

• CMakeLists.txt
  注意： 当时一个 bug 是因为 add_executable() 没有把 baz.cpp 添加进去，导致报错 undefined reference o xx

  cmake_minimum_required(VERSION 2.8)

  设置 C 编译器为环境中的 $CC

  set(CMAKE_C_COMPILER $ENV{CC})

  设置 C++ 编译器为环境中的 $CC

  set(CMAKE_CXX_COMPILER $ENV{CXX})

  include_directories(${PROJECT_SOURCE_DIR})

  project(main)

  add_executable(main main.cpp baz.cpp)
